[Evaluation of combined resection of aortic wall in lung cancer invaded aorta].
Left pneumonectomy with combined resection of aortic wall was performed for three patients with lung cancer invaded aorta. In clinical and pathological examination, the following results were obtained. 1: In all three cases, metastasized subaortic lymphnodes invaded to medial wall of the descending aorta. 2: Microscopically, invasion of aortic wall was limited to the adventitia adjacent to the muscle layer. We think that the resection of whole layer of the aortic wall was preferable. 3: The resections of aortic wall were performed under partial clamp of aorta in one case, and under total clamp with the use of cardiopulmonary bypass in two cases. If the area of invasion is wide, total clamp was recommended. 4: Two patients died of recurrent disease 56 months and 20 months after surgery. In the other one, postoperative empyema was occurred. He died of bleeding from the suture line of Dacron patch to the aortic wall three months postoperatively. Covering of the bronchial stump and the patch of the aorta should be considered to prevent postoperative empyema.
